actually I hadn't installed linux on my Pc yet, instead I used knoppix std which seems to operate like lenux.

the problem of using knoppix that it does not perform some commands as they must be.

for example: the last command, if we use it with -d option it must display the IP address but it does not do so.

another problem is that I an required to write a program to do some operations in the date of login displayed in last command and since I don't know how data are displayed using last command I will not be able to write that program.

what I need is if any one of you could show me a screen shot of text to the result of last command with some options and with out.
